secured in the hook will be securely held with no released.

Another object of the invention is the application ofa mechanism to automatically open thehook when the trip is thrown so that the trace will' be positively released When desired.

A further object is to provide a device'ot` this character that will form a partI of the Whittletree thus insuring strength andrigidity which areessential to the perfect operation of a hook of this nature. v y

The invention has for a still further object the production of the above results with the simplest possible mechanism and to so construct such mechanism that it will be simple of operation and in the number of its parts.

In the drawings forming portion of this specification, and in which like numerals of reference indicate similar parts in the several views,I Figure 1 is a top plan view ofthe possibility ot it being accidentally hook in a closed position showing" a portion of the whi'iiletree, Fig. 2 is a view of the saine, the hook beine; opened, Fig. 3 is an outer end view of the device closed, Fig. et is a front View of the device closed,"Fi;r. 5. is an inner `end view showingfthe whitlletree in cross section, Fig'. 6 is a longitudinal cross section ot the hook.

referring to the drawings, designates the outer extremity `of a whillietree on the end of which there is a. yforwardly .projecting arm 11. The arm 11 is longitudinally recessed at its outer end as at 14 and pivotally supports'intermediately of its length a lever 12 secured in position by the pin 13 in the re cess 14 of the arm 11. The lever 12 is forked at its inner end`15 in which is carried the ex tremity of a rod 16 upon 'the pivot pin 17. The rod 16 extends backwardly and is embedded in a recess 18 formed in the front face of the Whiletree 1@ lntermcdiately of Specification o'f Letters -Panlzent. Application inea May 2o,

l the length ofsaid'rod ashoulder 19 is formed in the recess again' whicl` is impmged one end of a sprmfr-20 carried upon the inner against theslioulder 19 by the engagement ol a pin 21 upon the inner end ot' the rod -16 and engaging,- the inner end of the spring,- 20. The tension of the spring 2O tends to draw the rod 16 centrally on the whitlletree 10.

UponA the outer extremity of the lever 12 is pivoted the-hook member 22 which is adapted to pass through the eye 23' carried upon the rear end of the trace 24. The free end of the hook member 22 engages the inner side of a partly depressed shoulder 25 formed upon the extremity of an arm 26 protruding forwardly in parallel with the arm 11 from the whitlletree 10.` The .iuner end of the arm 26 is forked as at 27 receiving therebetween a tup lever.28 carried upon the pivot 29.v The trip lever 28 eX- tends between the arms 11 and 2 6 and cng'ages the inneredges of the arms 11 and of the lever 12. A leaf spring 30 is disposed upon the inner edge of the arm 11 extending longitudinally thereof being raised at its the trip lever 2S.

In operation, the device is used as follows: l The eye 23 is engaged over the hook member 22. The member 22 is swung backwardly :1nd at the same time the lever 12 is pressed inwardly against the tension of the s ring 20. The trip lever 28 is now pressed 'ackwardlyover the spring 30 into engagement .withthe inner end of the lever 12 to hold [he lever in the same plane with the arm 11 and thereby prevent the hook member 22 from passing' from behind the shoulder above position and the tension of the spring 30 will have to be overcome to throw the trip lever 2S out 'of operative position. ,lVhenthe trace 24 is to' be released the trip lever 2S is thrown forward and the tension of the springH 2O causes the retracting of .the rod 16 which throw's the outer end of the lever 12 outwardly and withdraws the hook the eye 23 to slide oil' the free' end of' the member 22 and to disengage the trace.
